I've always seen this forum (or any forum) like a game of scrabble. Lots of ways to add words (or posts).
The best words and posts, at least from a making the game fun angle, are long words in open spaces as it gives the other players plenty of room to spring board from.
The worst are adding a couple of letters to a word. It might score points but doesn't help the game much.
For the forum, the equivalent of a long word in open space is a good thoughtful post that invites discussion. It's not "bait" or "engagement farming", it's encouraging good discussion.
And on the other hand, a snarky or mean post has the opposite effect - they discourage discussion.
It's one of the reasons I'm always harping on keeping discussion civil. It's not just the kind thing to do - it's better for discussion.
